उत्तर
- Both the strands of DNA double helix are complementary to each other.
- That is a number of bases on each strand are equal and complementary to each other.
- As adenine pairs with thymine; the number of adenine bases on one strand and thymine on another are equal in number.
Thus, on complete hydrolysis DNA gives equimolar quantities of adenine and thymine.
